During the American Revolution St George's Manor became the British Fort St. George. Situated at the mouth of the Carman River, the cannon from the Fort secured the waterway for the British who used the river as a supply route and also a source of lumber to be gotten from the nearby woods. 

The plaque reads "Under orders of General George Washington, two companies of the Second Continental Light Dragoons, commanded by Major Benjamin Talmadge attacked and destroyed Fort St George and captured the British garrison at this place on November 23, 1780."

Across the river on the west bank of Carmans River was the place called "Fire Place neck" or the place where fires where made. These fires, in even earlier days,  guided the whaling ships into the inlet to a safe place for the processing of the whales.

It would be a rare sight today to see whales off Long Island.
